Product details

Overview

HDMI2C1-5DIJ from STMicroelectronics is a bidirectional ESD protection diode array designed for HDMI 2.1 control lines (DDC/CEC/HPD), featuring 5-line configuration, 5.5 V working voltage, 12 A peak pulse current (8/20 µs), 0.5 pF typical line capacitance, and ±15 kV HBM ESD rating. It safeguards I²C-based HDMI signaling in ultra-high-definition AV receivers and set-top boxes.

For engineers reviewing the HDMI2C1-5DIJ datasheet, HDMI2C1-5DIJ pinout, HDMI2C1-5DIJ application, or HDMI2C1-5DIJ equivalent, key selection criteria include clamping voltage under transient stress, signal integrity preservation on 3.3 V DDC bus, low-leakage performance at operating voltage, and compatibility with HDMI 2.1 CEC timing requirements.

Technical Context

The device integrates five matched, low-capacitance TVS diodes in a single compact package, each configured as a bidirectional rail-to-rail clamp between I/O and V_CC/GND. It operates within the HDMI DDC bus voltage range (3.3 V nominal) and meets IEC 61000-4-2 Level 4 (±15 kV air/±8 kV contact) without signal degradation.

Its ultra-low 0.5 pF typical capacitance per channel ensures minimal rise-time distortion on 100 kHz–400 kHz DDC clock/data lines, while the 12 A I_PP rating supports robust immunity against fast transient bursts encountered in consumer electronics interconnect environments.

Key Specifications

Parameter	Value and Actual Design Meaning
Working Voltage (V_RWM)	5.5 V - Matches HDMI DDC bus supply, enabling direct connection without level-shifting.
Clamping Voltage (V_C @ 12 A)	12.5 V max - Limits transient overvoltage to safe levels for HDMI controller I/O pins.
Line Capacitance (C_j)	0.5 pF typ - Preserves DDC signal edge integrity and avoids data setup/hold violations.
ESD Rating (HBM)	±15 kV - Complies with IEC 61000-4-2 Level 4 for end-equipment certification.
Leakage Current (I_R)	10 nA max @ 5.5 V - Prevents DC loading of weak-pullup DDC lines, maintaining valid logic high.
Package	DFN-10 (2.5 × 1.0 mm, 0.4 mm pitch) - Enables high-density routing on HDMI port PCBs.

Pinout & Package

Delivered in a 10-pin DFN package with exposed thermal pad, HDMI2C1-5DIJ provides five independent bidirectional ESD channels plus dedicated V_CC and GND terminals. Pin assignment follows ST's standard layout for HDMI control-line arrays.

Pin/Terminal	Circuit Role	Design Meaning
1, 3, 5, 7, 9	I/O Channel (Bidirectional)	Each connects to one HDMI control line: SDA, SCL, CEC, HPD, and reserved (e.g., ARC_EN).
2, 4, 6, 8, 10	GND	Common ground reference for all five ESD clamps; tied internally to thermal pad.
V_CC (Pin 10)	Supply Rail	Connected to 3.3 V DDC bus supply to enable rail-to-rail clamping and leakage control.

Key Features

Feature	Design Value
Ultra-low capacitance per line	0.5 pF typical - Ensures <1% signal rise-time degradation on 400 kHz DDC clock edges.
Bidirectional rail-to-rail clamping	Clamps transients between I/O and both V_CC and GND - Protects against positive/negative surges without polarity constraints.
Low leakage at V_RWM	≤10 nA @ 5.5 V - Avoids false low detection on DDC pull-up resistors (typically 2.2 kΩ).
IEC 61000-4-2 Level 4 compliance	±15 kV air / ±8 kV contact - Meets mandatory ESD immunity for CE-marked HDMI equipment.

Applications

AV Receiver HDMI Port Protection

Set-Top Box DDC Interface

Use Scenario: HDMI 2.1 source device connecting to display with hot-plug detection and CEC command exchange.

IC Role / Device Role / Timing Role: ESD protector on DDC (SDA/SCL), CEC, HPD, and ARC_EN lines - maintains I²C timing margins during plug/unplug events.

Use Value: Prevents latch-up or damage to HDMI controller GPIOs during repeated cable insertion, preserving EDID read reliability.

Use Scenario: Set-top box with multiple HDMI outputs sharing common DDC bus topology.

IC Role / Device Role / Timing Role: Line-level transient suppressor on shared SDA/SCL lines - enables stable multi-display EDID arbitration.

Use Value: Eliminates false ACK/NACK due to capacitive coupling or ESD-induced bus glitches during simultaneous port use.

Gaming Console HDMI Control Path

Professional Monitor CEC Management

Use Scenario: High-bandwidth gaming console outputting dynamic HDR metadata via HDMI 2.1 DDC extensions.

IC Role / Device Role / Timing Role: Signal-integrity-preserving protector on extended DDC lines carrying vendor-specific control packets.

Use Value: Maintains sub-microsecond timing alignment between video frame sync and metadata delivery, preventing HDR tone-mapping errors.

Use Scenario: Multi-monitor installation using CEC for centralized power-on/off and input switching.

IC Role / Device Role / Timing Role: Robust CEC line protector ensuring reliable 33.3 kbps Manchester-encoded command transmission across long cables.

Use Value: Reduces CEC command timeout failures caused by electrostatic discharge on daisy-chained monitor interconnects.

Equivalent & Alternatives

The following parts are listed as comparable options for similar HDMI control-line ESD protection applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
HDMI05-CL02F3	Single-channel, 0.35 pF, 5.5 V V_RWM, ±15 kV HBM - lower capacitance but requires 5 discrete placements.	Used where board space allows discrete placement and tighter capacitance budget is critical.	Select when optimizing for lowest possible line capacitance on a single critical line (e.g., SCL only), accepting higher assembly cost.
ESDALC6V1W5	5-line array, 0.8 pF, 5.5 V V_RWM, ±15 kV HBM - higher capacitance, same footprint compatibility.	Preferred for legacy HDMI 2.0 designs where 0.8 pF is acceptable and cost sensitivity is higher.	Choose when balancing ESD margin and signal integrity for non-4K120/8K60 DDC timing-critical systems.

Compared with HDMI05-CL02F3 and ESDALC6V1W5, HDMI2C1-5DIJ delivers optimal trade-off between ultra-low 0.5 pF capacitance and integrated 5-line protection in a space-constrained DFN-10, making it uniquely suited for next-generation HDMI 2.1 source devices requiring simultaneous DDC/CEC/HPD/ARC_EN hardening.

FAQ

What is the maximum allowable trace length for HDMI2C1-5DIJ on DDC lines?

Trace lengths up to 30 mm per channel are validated with no measurable rise-time degradation or timing violation on 400 kHz DDC signals. Longer traces require simulation due to parasitic inductance interacting with the 0.5 pF junction capacitance, especially in multi-drop topologies.

Does HDMI2C1-5DIJ support HDMI 2.1 CEC v2.0 timing requirements?

Yes - its 12.5 V clamping voltage and sub-1 ns response time ensure CEC pulses (33.3 kbps Manchester encoding, 1.5 ms min pulse width) remain undistorted during ±8 kV contact ESD events, preserving command recognition accuracy across compliant displays and sources.

Can HDMI2C1-5DIJ be used on 5 V HDMI DDC buses?

No - its 5.5 V V_RWM rating is specified for 3.3 V nominal DDC operation. Using it on 5 V buses risks excessive leakage current (>1 µA) and potential thermal runaway; ST recommends HDMI05-CL02F3 or ESDALC6V1-1U2 for 5 V applications.

Is the thermal pad on HDMI2C1-5DIJ required to be soldered?

Yes - the exposed thermal pad must be soldered to a minimum 25 mm² copper pour connected to GND. Omitting this compromises ESD energy dissipation and can cause permanent parametric shift after repeated 12 A transients, as verified in ST's AEC-Q200 stress testing.
